通达信小波段买卖点主图指标（趋势型）指标公式

📅 2026-10-04

核心逻辑

该指标是一个趋势反转型指标，主要包含两部分： 1. **均线系统**：O1、O2、O3是三条指数移动平均线（EMA），对（收盘价+最低价）/2进行3日、6日、9日平滑处理，形成短期均价线；MMM是20日简单移动平均线作为中线参考。 2. **K线形态识别**：通过VAR1-VAR18系列变量识别连续8根K线的上涨/下跌形态组合，判断当前趋势状态。

买卖信号

- **买入信号（买）**：前一根K线处于下跌形态（连续下跌后反弹再下跌），当前K线出现上涨形态（连续上涨），即趋势由跌转涨的拐点 - **卖出信号（卖）**：前一根K线处于上涨形态，当前K线出现下跌形态，即趋势由涨转跌的拐点 - 配合K线颜色标记：收盘价在20日均线上方显示蓝色星号，下方显示绿色星号

用法

1. 当出现“买”字信号且K线显示蓝色星号（价格在20日均线上方）时，可考虑买入 2. 当出现“卖”字信号时，应考虑卖出或减仓 3. O1、O2、O3三条线多头排列（向上）时持有多单，空头排列时观望 4. 该指标适合中短线交易，侧重于捕捉趋势拐点
